Working on a project where I want to use ESP32 to measure current on three phases and temperature with DS18b20
and send it via udp for data collection
Is there a non invasive current transformer that has a I2C interface?
Thanks
Hello,
Have you tried a Google search? 
yes, I have already designed and built a system to monitor 68 vacuum pumps for amps and each phase and oil temperature that uploads the data thru udp to a spreadsheet.
As the esp32 is fairly bleeding edge the analog read is not there yet so using the non invasive ct are not practical at this time there is a company that makes various I2c based ct but their prices a ludicrous
I will keep looking
